The Radiation of the Stars

Abstract

MR. JEANS'S criticism of the dimensions of my equation, “radiation-pressure=gravity”, is clearly only a verbal matter. It may be preferable to expand the sentence so as to read, “force on material due to radiation-pressure=force on material due to gravity.” But statements that radiation-pressure is x times gravity have been commonly made in connection with the theory of the repulsion of comets' tails, and I thought the reader would have no difficulty in interpreting my statement in the same sense.
